Heavy DA trigger which makes the first shot more difficult. Glock and other striker fired guns much easier to shoot well. If not comfortable with DA/SA pistols it might not be the best choice. But,
On the Variant One Compact it’s a safety and decocker setup, which I like because you can carry like a 1911 and skip the long DA first pull if you want. Much better shooting with the single action pull.
I am having a Gray Guns short reset trigger kit put in mine. Haven’t gotten it back yet. Should make the DA pull better and the SA reset shorter. We’ll see.
It’s an accurate gun. Recoil in the .40 Compact is not terrible, and clearly better than with the Glock 23s.
I have owned three HK USP Compacts in .40 caliber, will probably keep the third just to have an HK. Why not. It seems well-made, with lots of cool European proof marks. Has been pretty reliable with 3 recorded malfunctions (all failures to feed) in probably several hundred rounds fired. But,
Broke the firing pin on my first one by dry firing. Very weak-looking firing pin design, but read that a run of firing pins was not heat-treated properly which may be the reason mine broke.
So much for HK “perfection “. I still wouldn’t dry fire mine much, or without a snap cap, just because of my breakage experience.
